Abstract (en)

[origin: EP0286725A1] An improved conveyor drive unit (150) with a method of operation thereof, which can be rapidly and easily mounted on a roller-type conveyor system and which, when arranged in series, can be sequentially stopped and restarted relative to predetermined parameters in the article flow along a conveyor path (56). In one embodiment, each drive unit (150) has an arm (52) which extends at a desired distance over an article conveyor path (56) which can be tripped at the occurrence of accumulation. A pneumatic valve (68) is operably coupled to the arm (52) for releasing air into an actuating cylinder (78) having operably coupled thereto a shifter rod (92). The shifter rod (92) is axially displaced by the actuating cylinder (78) which in turn releases a drive collar (102) from a keyed sprocket of the pinion gears (18) of a transfer mechanism or "module" (1) of the conveyor system. When the drive collar (102) is disengaged, the operation of transport mechanism or module (1) is thus halted.
